How to prevent script from running from a folder?

Question

linux

Do I always have folder
26534 ? Sl 136:08 /var/www/pravfelon/data/bin-tmp/phpkfeIDj_7o4pm6h2hxpljzo2 -c /var/www/pravfelon/data/bin-tmp/phpkfeIDj.c
A script is being launched that loads the system.
I delete these files from the folder all the time.
How can I prevent scripts from being written to this folder?
Can you delete the /var/www/pravfelon/data/bin-tmp/ folder
or is it needed?
Tell me, who means how to deal with this virus?

Answer 1

Well, cut the rights of the folder. At the same time, look who is the owner of the script and on whose behalf it is running - maybe it's time to change passwords.

Answer 2

Familiar virus however ;)
Mines quietly.
as long as you remove the virus, you can do so.
Check like this

If so, put it in cron
And treat sites;)
